Does anyone know this Stephen Plumlee

I have a copy of a will from Blount County Wills and Deeds Vol. 6 for Stephen Plumlee. The date is Jan. 1847 and is signed with Stephen Plumlee's "mark". It mentions his wife Esther and children: John Plumlee, Polly McGrew, Rebecca (looks like Barton), Peggy, Abby (looks like Kinning), Elizabeth Ray and heirs of son William. Does anyone know which Stephen this might be? I really don't feel that this is our line, due to some of the dates and the statement "heirs of son William" (ours was still living at the time) but I would like to be able to rule out this line. Appreciate any help. Penny
